Does the color of a liquid affect its evaporation rate? We wanted to find out if the color of a liquid would affect how fast or slow it evaporated.
We predict that the color of a liquid will affect its evaporation rate, and also that the darkest colored liquid will evaporate the quickest because it will absorb the most heat.
We added drops of yellow, red, black, blue, and purple food coloring into separate cups and kept one cup clear.
Then we heat 2 ½ cups of water in a microwave for 7-8 minutes and took temperature of the heated water. Later we added about 15 milliliters of the hot water to the cups, including the clear cup. We placed the cup that was bigger than the initial cup over each of the containers of colored and clear water. After 5 minutes observe and record the evaporation rates with a scale, measuring the inside contents. Compare and contrast the results. Record the volume and temperature change in specified data tables.
